I try with argument (-a <driver,port> Auto configure PSP), but it still can't connect:

Yes, the application should report "NUT release:" and "NUT driver: (version:)" info in the About tab, but now this fields are empty

The problem is that I changed the "ups name" in /etc/nut/ups.conf and /etc/nut/upsmon.conf, but I did not do it in /usr/sbin/upssched-cmd script (default is "Ups="[email protected]"). Now everything is OK.
